Effect of Activating Blood to Resolve Stagnation on Cells Expressing CD34 and Vascular Endothelial Growth Fac-tor in Rats with Acute Myocardial Infarction / 中国康复理论与实践

ABSTRACT

Objective To explore the effect of Activating Blood to Resolve Stagnation on the expression of CD34 and vascular endotheli-al growth factor (VEGF) in rats with acute myocardial infarction. Methods 32 Sprague-Dawley rats were randomly divided into sham opera-tion group (A, n=8), model group (B, n=8), Xuesaitong Injection + granulocyte colony-stimulating factor (G-CSF) group (C, n=8) and G-CSF group (D, n=8). Corresponding medicine was given to each group 3 hours after modeling, for 6 days. Pathomorphological changes were observed through HE staining, and the expression of CD34, VEGF and Ki-67 were observed through immunohistochemical staining. Re-sults The expressions of CD34, VEGF and Ki-67 were higher in groups B, C and D than in group A (P0.05). Conclusion The expression of CD34 and VEGF in-creases with Activating Blood to Resolve Stagnation method, which is superior to using G-CSF only. Activating Blood to Resolve Stagna-tion may play an important role in the treatment of acute myocardial infarction.
